You Got Hacked By Your Mouse
In the world of cybersecurity, we often talk about phishing emails, zero-days and nation-state actors. But sometimes, the most dangerous threats hide in plain sight right on an official download page. That’s exactly what happened recently when attackers compromised the Endgame Gear OP1w 4K V2 mouse configuration tool and embedded it with Xred, a stealthy Windows-based Remote Access Trojan (RAT).
Let’s unpack what happened, how it went unnoticed for weeks and why this should alarm everyone not just gamers.
A Classic Supply Chain Breach
Between June 26 and July 9, 2025, users who downloaded the OP1w configuration utility from the official Endgame Gear website unknowingly installed a backdoor. This wasn’t some sketchy third-party mirror or pirate site it came directly from the company’s own CDN.
The payload? Xred malware, disguised as a system driver under the name Synaptics.exe. The malware operated quietly, collecting system information, creating persistence via registry keys and even enabling USB propagation. It masked itself using metadata that claimed it was a Synaptics pointing device driver a clever bit of camouflage to dodge basic scrutiny.
What Makes This So Dangerous?
This isn’t just another malware dropper. This is a supply chain compromise and those are notoriously hard to detect even harder to prevent. Users trusted the source. Antiviruses didn’t flag the installer immediately. And because the installer looked legitimate, many gamers went ahead and ran it without hesitation.
Think about this: Endgame Gear is a respected name in the gaming hardware space. If their software gets compromised, what does that say about smaller vendors with fewer resources and weaker infrastructure?
How to Know If You’re Infected
If you downloaded the configuration utility during that window, here’s what you should do right now:
- Enable hidden files on Windows.
- Navigate to:
C:\ProgramData\Synaptics\ - Look for a file named: Synaptics.exe
- Right-click → Properties → Details tab.
- Infected: Shows “Synaptics Pointing Device Driver” as the product name.
- Clean: Shows “Endgame Gear OP1w 4K v2 Configuration Tool”
- Check file size:
- Infected: ~2.8 MB
- Clean: ~2.3 MB
If you’re infected, delete the folder, run a full antivirus scan and monitor your system for any unusual behavior.

Endgame Gear’s Response
Endgame Gear removed the compromised tool by July 17 and published a Security Advisory. They claimed no customer data was accessed and that only the installer download was affected. They’ve since centralized downloads and promised to:
- Scan all future uploads with multiple anti-malware tools
- Begin using SHA-256 checksums
- Eventually sign their software with digital certificates
Good steps but those promises came after users were already exposed for over two weeks. That delay allowed the malware to silently spread and operate on potentially thousands of systems.
The Bigger Picture
Let’s be clear: this wasn’t just a breach of a mouse tool. This was an attack on trust the very thing that keeps the software ecosystem functioning. Every time we download a tool from an official site, we assume it’s safe. That assumption just took a hit.
And this isn’t a one-off. We’ve seen similar compromises before ASUS Live Update, CCleaner, SolarWinds. Hackers are no longer trying to break in through the front door; they’re building malware into the welcome mat.
What This Means for Cybersecurity Pros
As someone deeply involved in cybersecurity, this attack highlights two key realities:
- No vendor is too small or too niche to be a target.
- Supply chain security must become a priority, not an afterthought.
It’s time we push all software vendors especially those distributing binaries to:
- Use code signing consistently.
- Provide hashes for public verification.
- Employ independent audits of their release infrastructure.
Users also need to get more vigilant. Verify hashes. Use sandbox environments for new tools. And never assume “official” means “safe.”
Final Thoughts
The OP1w compromise is a reminder that even the tools we trust most can turn against us. If you’re a gamer, a developer or a fellow security professional, take this as a wake-up call.
